Application filed December 27, 1915, Serial No. 68,744. Renewed March 10, 1919. Serial No. 281,795.

To all whom it may concern:

Be it known that I, ALBERT E. DURLAND, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain newand useful Improvements in Box-Assembling Apparatus, of which the following isa specification.

This invention relates to improvements in box-assembling apparatus.

The principal object of the invention is the provision of simple and conveniently operated devices for holding the boXends in proper spaced alinement so that the boxsides may be handily nailed in place. Footoperated devices are provided for turning the box-parts to successively present the sides and bottom of the box uppermost whereby the operator may most readily secure the parts together.

Another object of the invention is the provision of devices for presenting a plurality of box-ends in position to be easily grasped by the operator to economize his time and to make for the maximum efficiency of the machine.

Still further objects of the invention will be evident in the following specification.

In the accompanying drawings, Figure 1 is a view in front elevation of a box-assembling machine embodying my invention. Fig. 2 is a view substantially in side elevation of the same, although taken on section line 22 of Fig. 1. Fig. 3 is a partial plan View of said machine illustrating the box-end clamping mechanism. Fig. 4 is a detail side view of said boX-end clamping mechanism.

Fi 5 is an end view of Fig. 4. Fig. 6 is a c etail view in front elevation of the boxturning devices and adjacent parts. Fig. 7 is a view on sectionline 7--7 of Fig. 6. Fig. 8 is a view in longitudinal section of oneof the supportingknees for the box-ends. Fig. 9 is a view on section line 9-9 of Fig. 8. Fig. 10 is a perspective view of a modified form of an element of the machine.

Referring to said views, wherein similar reference characters denote similar parts in the several views, the reference numeral 10 indicates the front upright posts and 11 the rear posts of a substantially rectangular frame. Said posts 10 are connectedby horizontal frame-bars 12 and 13, and posts 11 by suitable frame members. while transverse frame-bars such as 14: and 1 5 and various bracennembers are so disposed where needed to provide a rigid framework of relatively light and rigid character.

Vertical standards I6, 16 are providedat each side of the frame supported at their lower ends upon the frame bars 14: and are connected at their upper ends to the respective rear post 11 by horizontal brace-bar 17 Said standards are formed with guide-slots 18 and 19 in which longitudinal rod 20 and superposed arbors 21 of a vertically reciprotion 22 (see Fig. 2) which provides a bearing at each end of the machine for a camshaft'26 and a parallel alinement rod 27.

A semi circularly bowed support 28 is provided for the inner end of each said arbor having an open side facing to the front and slidably connected intermediate its ends to the rod 27 and at its lower end to the rod 20.

A clamping plate 30 is rigidly mounted upon the inner extremity of each of said arbors 21. Said carriage is further provided with clamping members 31 adapted to ooact with the plates 30 to secure a box-end in operative position therebetween. Said members are secured to bowed supports: 32 of similar configuration to supports 28 and have their lower end slidably mounted upon the rod 20 while their rearward intermediate portion is similarly associated with the shaft 27, and

adapted to be adjustably and pivotally secured thereto by set-screw 32". Said supports 32 are further formed with a rearward apertured extension 33 through which the rod 26 extends, as clearly shown in Fig. 4'. Upon each said extension 33 upon the sideopposite to which the respective clamping members 31 are positioned, is a cam 35 with which is engaged an integral finger 36 of a set-collar 37 fixedly mounted on the rod 26.

(Said extension and cam are pressed in yielding engagement with said collar by a coil-spring 38 surrounding rod 26 and confined by set-collar 40. The effect of these "just-described devices is such that the spring 38 normally presses the clamping member toward the respective plate 30 to clamp a box-end therebetween, the support 32 having a slight rocking movement upon the rod 27. When the rod 26 is rocked in the proper rotary direction through the crank-lever 41 manipulated by the operator through the pull-rod 4-2, the finger 36 will react upon the inclined face of the cam 35 and force the extension 33 against the pressure of the spring 38 to separate the clamping-members 30 and 31.

Said carriage as a whole is arranged to be reciprocated in vertical directions, the rod 20 and the arbors 21 being guided in slots 18 and 19, as aforesaid. Such movement of the carriage is accomplished by the operator pressing with his foot upon the hinged treadle 43 which is connected intermediate its length through rings 45 with the levers 4:6'which arefulcrumed at 4:7 and connected with the vertical bars 23 through links 48.

A counterweight 50 serves to equalize the weight of the carriage, being connected thereto by flexible connections 51.

Fixedly secured upon the respective arbors 21 is a sleeve 52 to which is rigidly secured or integrally formed a star-wheel 53 having four equally spaced radiating arms 55. Said arms are adapted to engage, in turn, an adjustable stop 56 upon the upward travel of the carriage, and cause the arbors 21 to make one-fourth of a revolution at each upward stroke of the carriage. The inner end 57 of said sleeve 52 is made square in cross section, as shown in Fig. 7, while one side of said guide-slot 19 which engages with said squared portion 57, is formed of a strlp 58 hinged at one end 59 while its other end is retained in yielding engagement against the respective flat surfaces of the end 57 by a spring 60. Thus the pressure exerted by the strip 58 upon the sleeve tends to maintain the star-wheel in suitable relation to the stop 56 to effect the movements required.

.As the box-ends are seldom of square configuration, it is desirable to provide limit stops for the carriage at different elevations at each alternate reciprocation of the carriage and to take the impact and weight of the carriage so that the same is not borne by the boX-ends. To this end, slidably adjustable stops 61 and 61 are mounted upon said sleeve- 52 extending in diametrically opposite directions and arranged to hit upon a projecting bracket 62 secured to the frame at each alternate quarter-turn of the arbors: 21 to limit the downward movementof the carriage. At each intermediate downward reciprocation of the carriage an adjustable screw or other stop 63 is provided on the side of the frame to be engaged by the rod 20 on the downward stroke.

Supported on horizontal longitudinal frame-members are horizontal transversely arranged knees 65, 65 of which the middle one 65 is fixedly secured intermediate the length of the frame while the outer knees 65 are adjustable longitudinally of the frame through bolt and thumb-nut connections, indicated at 66.

Referring to Figs. 8 and 9 wherein said knees are illustrated in detail, it will be seen that in the form now considered, the horizontal knee 65 is surmounted by a metal casing 68 having a chamber 68 formed with a slot 70 in its upper wall. A metal block 67 bifurcated at each end is adjustably secured along the length of said chamber by a bolt 71 received within the forward bifurcation of the block. \Vithin the rear bifurcation, a dog 72 is pivotally secured at one end at 73 while its opposite end 75 is normally pressed upwardly to protrude through said slot 70 by a spring 76, said end 75 forming a stop to guide the positioning of the boxends quickly upon the knees before the clamps 30 and 31 are engaged therewith.

77 indicates an inclined or other shelf whereon are piled the boards within easy reach of the operators hand for nailing upon the box-ends to form the side walls of the boxes. The box-ends may be similarly positioned upon shelf 77 so as to be readily grasped by the operator, but I prefer to provide a separate rack and operating mechanism whereby such box-ends may be mechanically presented to the operators hand.

Referring particularly to Figs. 1 and 2, the reference numeral 78 indicates an inclined rack adapted to retain the box-ends 79 in vertical position, whereby the latter are caused to move forwardly toward the front open end of said rack as the foremost b0x-ends are removed. Abutment blocks 80 are provided at each side of said open end. of the rack against which the front box-end engages, said blocks 80 being adjustable in the side-walls 81 of the rack by means of thumbaiuts 82.

83 indicates a plunger adapted to engage the lower end of the box-ends, which is operated in vertical directions by the upward movements of the main carriage, by means of a lever 84 fulcrumed at 85 connected by a link 86 to an end of a lever 87 pivoted at 88 whose opposite end is engaged by the rod .27 when the carriage is actuated in upward emme 'Ihe plunger is arranged to engage either two or three of the box ends, or any number desired, by adjusting the blocks 80 through.

said thumb nuts 82. Similar feeding devices for the box sides may be'provided either at the side of the operator or superimposed upon the machine,as upon the shelf 77.

It will be noted that intermediate clamping plates 90 are provided which are utilized when the box is to be made with a transverse partition there1n,as 1s customar1ly provided in some forms of fruit boxes.

In this case the knee is built rigid upon the frame and the supports 28 and 32 may be fixed relative to said knee, excepting that the support 82 is adapted to be opened and closed through the partial rotation of the cam rod 26, as is the case with the clamping plate supports heretofore described.

In operation, the operator first grasps two of the box-ends and positions them upon the knees 65 and alines them against the adjustable stop 72 which is yieldingly thrust above the plane of said knees. In the case of a partitioned box, it will be under stood that three of the box-ends are utilized, one being positioned upon the knee 65 as indicated in dotted lines in Fig. 1.

The operator then grasps the pull-rod 42 to actuate the cam-rod 26 to close the clamping members 31 and secure said box-ends against the plates 30. He then takes one or more of the box sides resting upon the shelf 77 and nails them upon the top, uniting the rectangular sides of the box-ends. After the said box sides are secured, the operator pushes with his foot downwardlyupon the treadle 43, which actuates the carriage upwardly. In the upward movement of the carriage the respective arm 55 of the starwheel 53 engages the adjustable stop 56 and causes the arbors 21 to turn one-fourth of a revolution, turning the box-ends with the nailed side an equalamount whereby, when the carriage returns on its downwardstroke, the box-ends will again rest on the knees 65 in position to have the box sides nailed upon its second side.

After the second side is nailed securely, the carriage is again elevated to cause the partially completed box to present one of its unfinished sides at the top, whereupon the third side is nailed thereon, and the box is complete with the exception of nailing on the cover, which is done after the box is filled with its contents.

As the box-ends are usually rectangular in shape but longer in one dimension than the other, the stops 61 and 61 are regulated to support the weight of the carriage upon the brackets 62, when the longer dimensions of the box are arranged in vertical directions. In this position the box-ends are brought up against the stop 72.

When the box is turned to present the longer dimensions of the box-ends in horizontal directions, the carriage will descend somewhat lower and the stops 63 are adjusted to interfere with the rods 20, while the stops 61 and 61 are rotated with the arbors 21 to horizontal directions.

The box-ends, as they again rest upon the knee 65, extend over the stop 72 whereupon the latter is yieldingly pressed down within the sltt 7 0 and does not interfere with the support of the box-ends upon the knees.

Said knees 65 may be slidably adjusted longitudinally of the machine to accommodate the same to various lengths of boxes. The corresponding parts, such as the clamp ing members 30 and 31, with their supports, are also adjusted to conform to the various sizes of boxes assembled.

Where relatively narrow boxes are to be formed, such as are used for peach or cherry-boxes, the clamping members 30 are desirably formed of rectangular configuration, as shown in Fig. 10, of lesser dimensions than the box-ends so that the box-ends will extend outwardly beyond the clamping members and rest upon the knees without interference.
